The NYC Department of Corrections has stated that Rikers Island has no evacuation procedure for any of the 12,000+ prisoners located on the island, regardless of the fact that is surrounded by either a mandatory or suggested evacuation zone. Also Rikers Island is partially built on an old landfill making it more high risk for flooding.

Call-in to NYC FEMA office - 212-680-3600 (press 1 for regional representative) - or NYC Department of Corrections Information Line - 718-546-1500 (follow the prompts for a representative) starting at 3pm TODAY 8/27! Keep in mind this is a federal agency. Be safe!
